Answer:
24 
Step-by-step explanation:
Area of parallelograms is :
A = b x h
The height must be a line perpendicular to the base.
The slant measuring 5 is not perpendicular to the base.
A = 6 x 4
A = 24
Okay so basically, you subtract 18 on both sides since the 18 doesn't work, making the equation
<span>x</span>²<span> - 10x = -18
So then you add (b/2)</span>²<span>, which is 25, to both sides, to get
</span><span>x</span>²<span> - 10x + 25 = 7
</span><span>After this, you factor.
</span><span>(x-5)(x-5) = 7
</span><span>Then you simplify.
(x-5)</span>²<span> = 7
Then you solve for x.
</span>√(<span>x-5)</span>²<span> = </span>√7
x-5 = (+ or -)√7
~ x= 5 (+ or -)√7 ~
Hope this helps!
